anyone installing these in a 135i ?
I dont track or race my car, just a weekend car.
Only mods i plan to do in the future : new intake, berk exhaust and possibly cobb N55 chip.
Is this catch can nice to have to preventive maintenance ?

does this also mean i can extend oil change intervals ? i do change oil every 5,000 kms.

I dont think so. The only way to extend the oil change intervals is using a quality fully synthetic oil, like Castrol Edge, Red Line,Royal Purple,Pennzoil Platinum or similar. I personally use Castrol Edge With Titanium. I do my oil change intervals in my 135i, at 3/3.5K miles, but you can go to 5-6K miles and you will still be on the safe side,I just like my oil to be always as fresh as possible,it all depends on your driving style.
